congrats! just dont breath in too much of that modeling glue
oh btw... rustoleum makes a great aged bone color spraypaint called "fossil"... I used it on all my lindbergs and that way they werent super brilliant white (tea and coffee staining do not work on this type of plastic so paint and airbursh are your best bets)...
I am amazed with myself for something as lame as making a box jump, spit smoke and growl. This stuff is off the charts remarkable. I wish I had a quarter of your talent!
I have 8 rejected servo plates for the Lindberg skull. These are pre-cut for Bob's 3-axis configuration. The only problem with them is the threads are all stripped out . You can drill a bigger hole and retap or use a small nut and bolt. Originally they were for 5-40 screws.
Those that already got their plates for the bucky, please do not ask for them. I will be shipping these out next week, or if you want, and you can wait two weeks, I will include the axis rod and bracket.
And just out of curiosity, for those that got the original bucky plates? Are they going to work for you? Look for your bracket and axis rod in two weeks. We finally got the new rod to work (better adjusting).
Please send me a PM. I will only respond back to PM for these requests.
Some good news and some bad news...
Folks, we had a failure today on one of our 3 axis skulls using the aluminum rod axis. The rod snapped at the base where the rod end is mounted. Basically, at the .185 diameter to the angle cuts to allow the rod end to move more freely. We took the other two off line and notice one rod .185 was bent about 5 degrees off center axis. And the other had some stress cracks developing. This was after 38 hours of testing.
The good news is - the new rod dimensions work and there is plenty of clearance to use 4-40 rod connectors and the like.
We're going to go back to using steel bolts (McMaster Carr 91247A234) to manufacture the rod axis. We plan to start machining these parts early next week. The servo brackets are done.
So for those of you that already got your plates, look for the new rod and bracket sometime during the end of Jan. For those of you that elected to hold off and have everything delievered at once, around the first of Feb.
Again, no charge for this and just post pictures of how it works out for you.
Also, for those of you that PM about what servo to use - if you received a bucky plate and plan to use it in a bucky skull, use the HS-625MG (the 425 will work, but you have to have the center axis to the servo plate dead center - the plates we gave you are not dead center). For those of you that plan to use the Lindberg skull, you can use HS-425BB.
I will send directions out on how to use the HS-625MG with the new rod. You have to mount to servos on the back side of the plate....
Has anyone tried using a little larger diameter rod bearing.. 3/8", 7/16" or even 1/2" opening for strength? That would make the rotate arm a little bigger, but would going with at least 3/8" vertical rod make it less seceptible to fatigue or is it a matter of "neck" clearance, letting the skull tilt/nod without 'bottoming out' on the rod? Wondering..
